DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wing-type luggage transport vehicle in which a ceiling and upper left and right side walls of a box-shaped luggage compartment are flipped up to facilitate cargo handling.

[0002]

2. Description of the Related Art A conventional luggage carrier of this type is called a wing body or a flap body. A left wing, a right ceiling, and a right upper side of a box-type luggage compartment are integrated with a left ceiling and a left upper side. And right and left wings, and left and right driving devices for individually swinging and driving these left and right wings.

In such a wing-type luggage carrier,
Since the side surface is released, the cargo handling is mainly performed by a forklift, and it is difficult to work the crane, which is the cargo handling from above.

[0004] On the other hand, conventionally, a so-called center-folding type wing is used in which a wing is formed as a center-folding type, and a part of the wing is bent so as to be able to be loaded from above when the wing is flipped up. There is a vehicle.

Usually, the left and right wings have the same width, but the ceiling width of one wing is set to about 2/3 of the whole and the ceiling width of the other wing is set to about 1/3, and the ceiling dividing line is offset. In addition, there is a so-called center offset type wing transport vehicle in which a large wing is flipped up by a large hydraulic cylinder device to a position above a small wing to release a space above a cargo space.

[0006] Further, a slanted column type transport vehicle in which the body column of the wing portion can be tilted left and right, and the column is tilted outwardly of the vehicle body in a state where the wing is flipped up to release the upper surface of the luggage compartment. There is.

[0007] When the previous SL in foldable wing, there is a problem that the rigidity of the wing in the closed state of the luggage compartment is reduced.

Further, there is a problem that the manufacturing cost of the wing increases to compensate for the rigidity.

Further, in the case of the center offset type wing, the wing on the side where the ceiling is released becomes large, so that the cylinder device for driving the wing becomes large and the left and right sides with respect to the luggage compartment. , Ie, the crane operation can be performed only from the large wing side, and the crane operation cannot be performed from the other wing side.

Further, in the case of the above-mentioned inclined column type, since the column and the wing must be inclined at the same time, a large-sized cylinder device is required, and the column is swingable, so that the rigidity is reduced. Alternatively, there is a problem that manufacturing cost and weight increase to compensate for this rigidity. In contrast, as disclosed in the actual fair 5-17299, JP-portal frame to the rear end of the "loading platform is erected, erected on the front end of該門type frame and loading platform Between the front wall and the front wall are provided left and right loading roofs formed in a substantially inverted L-shape in cross section to cover the upper surface and side portions of the loading platform, and the base ends of the left and right loading roofs are connected to the gate frame and the front wall. The left and right roofs are rotatably connected to the upper edges of the left and right roofs by a cylinder interposed at least between the left and right cargo bed roofs and the upper edge of the gate frame or the front wall. In the cargo truck roof opening / closing device for a truck, the middle pivot portion located at the top of a bell crank having pivot portions at three positions in a triangular shape is provided with a base for the left and right cargo roofs. The end is pivotally mounted coaxially and pivotally on a pivot axis, and the lower side of the bell crank is on the side of the loading platform. A base end of a primary operating cylinder that opens the cargo bed roof upward at a substantially right angle or a distal end of a piston rod inserted into the primary operating cylinder is pivotally attached to the pivot portion at one end. The tip of the piston rod of the primary operating cylinder or the base end of the primary operating cylinder is a lower surface of the bed roof at a position where the piston rod is in a contracted state when the bed roof is closed. A secondary operation for further widening the opening degree of the cargo bed roof is pivotally attached to the vicinity of the side part of the car and rotatably pivotally attached to the other end of the bell crank located inside the cargo bed on the lower side. The base end of a cylinder for use or the tip of a piston rod fitted in the cylinder for secondary operation is pivotably connected to the tip of the cylinder for secondary operation or the cylinder for secondary operation. The base end of the carrier A cargo which is rotatably connected to a portal frame or a portion near a side of an upper edge portion of a front wall at a position where the piston rod is extended when the root is closed. A carrier roof opening / closing device for an automobile "has been proposed.

In the truck roof opening and closing device for a truck, the interference between the left and right cargo roofs and a support member positioned at the center in the width direction of the cargo roof is prevented.
In order to increase the opening angle, an intermediate pivot located at the top of the bell crank may protrude upward from the upper surface of the bed roof, and / or the support member may be positioned below the upper surface of the bed roof. I try to draw in. For this reason,
There is a problem that the overall height of the bed roof opening / closing device is increased, and the height of the cargo room space below the roof is limited.
In addition, since the roof has irregularities, there is a problem that the air resistance increases when the automobile is running at a high speed, and when the support member is recessed from the top surface of the roof, rainwater tends to concentrate there.

The present invention has been made in view of the above-mentioned conventional problems, and has a structure in which a rotation shaft at a base end of a wing projects upward.
The swing angle when the wing is opened can be increased without causing
And the top of the roof should be horizontal
Without impairing the rigidity can wing or strut to the granulation, and without using a large cylinder device, further, even from the left or right wing side, it provides a wing type load carrying vehicle handling is possible by crane The purpose is to do.

[0012]

According to the present invention, a left wing in which a left ceiling and an upper left side surface of a box-shaped luggage compartment are integrated, a right wing in which a right ceiling and an upper right side surface are integrated are provided. In a wing-type luggage transport vehicle having left and right driving devices that swing the wings around the centerline side in the front-rear direction of the ceiling of the box-shaped luggage compartment, at least one of the left and right driving devices corresponds to A swing bracket disposed on the vehicle body side so as to be swingable in a vertical plane by a first rotating shaft at substantially both end positions of the wing in the vehicle longitudinal direction, and a first cylinder for driving the swing bracket in a fixed angle range A device, a second rotating shaft that supports the wing so as to be swingable in a vertical plane, and is disposed between the swing bracket and the wing in the vicinity of the first rotating shaft; The swing A second cylinder device for driving the wing in a fixed angle range with respect to a racket; and a swing angle of the swing bracket by the first cylinder device, and a second cylinder device. The sum of the swing angles of the wings with respect to the swing bracket is set so that the tip of the wing when fully opened is located substantially above the center line .
When the wing is closed, the second axis of rotation is
The vehicle body width direction and the horizontal direction with respect to the first rotation axis.
At a position adjacent to the outside, it is parallel to the first rotation axis,
The wing, the first and second rotation axes are positioned on substantially the same horizontal plane.
The above-mentioned object is achieved by disposing.

In addition, the first and second cylinder devices are
The wings may be arranged in the space inside the end of the wing in the front-rear direction of the vehicle with the wings closed in a vertical direction and arranged in parallel with the wings closed.

[0014]

According to the present invention, at least one of the left and right wings is swingably supported by the swing bracket, and the swing bracket is swingably supported by the body side. The first cylinder device swings with respect to the body side, and the wing supported by the swing bracket is rotated by the second cylinder device.
It swings with respect to the swing bracket.
That is, the wing is opened in two stages.

Therefore, the wing is once jumped up so as to release the side surface like a normal wing, and when cargo handling by a crane is necessary, it is further jumped up until the ceiling is released. Here, the wing itself has the same structure as that of the related art, and there is no need to use a center-fold type or the like.

If the wing drive devices are provided on the left and right wings respectively, cargo handling by the crane from the ceiling is possible from either the left or right side. Swing the base of the wing
The second rotating shaft supported swingably on the racket is

When the wing is opened, the second rotation axis is about the first rotation axis.
As it swings and moves above the roof, the second rotation axis is reserved.
To avoid interference with support members at the center of the roof.
The height of the device does not need to protrude
Can be. Therefore, the height of the luggage compartment can be increased.
You.

Further, since the wing is driven in two stages by the first cylinder device and the second cylinder device,
There is no need to make these cylinder devices large. Therefore,
It is also easy to create a mounting pace for the cylinder device.

In particular, according to the second aspect, the first and second cylinder devices are vertically overlapped and parallel to each other inside the front and rear ends of the wing when the wing is closed. As a result, there is no need to provide a new mounting space as compared with the conventional cylinder device.
